Re: Pigment Or Bacteria? The Idea Of 'Color' In Fossil Feathers Gets A Rethink



Why the damned sexist comment? You only show your bias.

not good science. This paper is based on an experiment with chicken feathers to show that such microscopic structures can be made by growing bacteria on chicken feathers. So what. Now bury it in a wet anaerobic sediment for a 100 million years and see then see if you get these structures as well as that they form such elegant patterns over the body of the animal, emulating a very naturalistic design and rational topography along the flight feathers and such...

The approach, IMO, just doesn't fly.



She is cute though and will one day do a great job on a discovery channel docudrama.
